If your phone or SIMcard is lost or stolen and automatic recharge is on, this could be a serious problem.

To prevent this, log in to your account and activate the option to block your service immediately after you notice your phone or SIMcard is missing. You can find this option in the My SIMCards menu. Your OneSimCard service for this SIMcard number will be instantly blocked. The remaining balance on your lostSIM can be transferred to another SIMcard on your account or you can order a replacement SIM card if you would like to keep your phone numbers from the lost SIM.

Yes, you can! Our Refer a Friend program is available to all OneSimCard active account holders. For each friend you refer that purchases new service, you will receive $10 ($5 for rentals) deposited into your 1SIM Money Fund.

You can then use these bonus awards to recharge your airtime or use toward any other purchases. There are no limits to the number of friends you can refer or the bonuses you can receive!

In addition, your referred friend will also receive a 5% discount on their initial order, excluding airtime.

I have Range Roamer (Rangeroamer, Chit-Chat), I-Roam ( Iroam), Expo Mobile, Brighttel or iKappa SIMcards with numbers starting with +372. Can I switch to become OneSimCard customer?

If you currently have RangeRoamer (Range Roamer or Chit-Chat), I-Roam, Expo Mobile, Brighttel or iKappa SIMcards with the country code +372 ( Estonia) and can't get a service from the vendor you purchased the SIMcard from and thus having problem, you can register the SIM with OneSimCard.com and keep the phone number of the SIM.

As a welcome bonus OneSimCard will post $10 free balance on your account. You will also get free 30 day US or Canada PEN.

Besides this, generally, OneSimCard can be used on any cruise ship when the ship is close enough to shore so the cell tower signal can be picked up by the phone. The ship should be within at least 1 mile from the coast for your cell phone to pick up a signal. Service will work only when the phone is close to a country where OneSimCard provides international roaming service. Rates are the same as if a call was made from the shore of the country you are near.

We allow moving balances from one SIMcard to another in the following cases:

Corporate Accounts - anytime.

Individual Accounts - only when a SIMcard is lost or stolen. The remaining balance from your lost or stolen SIMcard can be transferred to another SIMcard on your account or you can order a new SIMcard if you would like to keep your original European number from the lostSIM.

Can I move Personal Extra Numbers (PENs) between SIMcards in my account?

Yes, you can move PENs within both private and corporate accounts. There is a small fee per PEN transfer which will be deducted from the SIMcard the PEN is being moved to. If there is not enough money on this SIM, the fee will be deducted from the SIM the PEN is being moved from. If neither SIMcard has enough balance, you’ll have an option to recharge. Transaction records will be posted under the History menu.

What is the difference between OneSimCard Plus, OneSimCard Data & Roam and OneSimCard Europe & More SIMcards?

All 3 OneSimCard SIMs work in a very similar manner. They all use an Estonian Mobile Number as the primary number and offer a Free US or Canada PEN for 30 days. All OneSimCards also offer many additional features such as Global Concierge, 24/7 Live Technical Support, SIM VOIP and Apps for iPhone and Android.

The main difference between the 3 SIMcards is that OneSimCard Plus offers Voice and SMS Text Messaging in many more countries. The OneSimCard Data & Roam is recommended mostly for Internet Data on iPads, Smart Phones, Mi-FI devices and generally offers lower Internet Data Rates and Data Services in many more countries . For some countries like Canada, Cuba, Brazil and a few others, the OneSimCard Data & Roam offers lower calling rates.

The OneSimCard Europe & More was specially created for European travelers and offers our best calling rates to the US & Canada, from the 40 included countries, all with easy Direct Dialing, while OneSimCard Plus and OneSimCard Data & Roam utilize callback.

OneSimCard Plus, OneSimCard Data & Roam and OneSimCard Europe & More also operate on different networks in many countries.

No. OneSimCard service is a prepaid service. You will not be able to spend more than you put on the SIM, except when you set the automatic recharge of the SIM. There are three simple ways to add funds to the balance of the SIM: from on-line, from the mobile phone and by setting up an automatic recharge. This pertains to both - purchased SIMcards and rentals.

Your OneSimCard global SIMcard and European phone number will never expire as long as you make at least one call every two years. If you fail to make or receive at least one call every two years, your OneSimCard global SIMcard and European phone number will expire and you will not be entitled to a refund even if at the time of expiration your account had a positive balance.

However, the funds on the SIMcard will expire 10 months from your last recharge and will not be refunded to you. The minimum recharge amount is $25. By simply recharging at least once every 10 months your balance will roll over. If your balance does expire, it will not be refunded to you but all you need to do to get the service working again is to log in and add funds to your SIMcard. If you set up the automatic recharge, it will be canceled if you allow the funds to expire, so you will need to set automatic recharge up again once you recharge your balance.
